HashChain

Peergame uses a secret key with SHA-256 to generate a chain of 1,000,000 hashes.

Each round seed’s hash equals the previous round seed.

For example, 1,000,000th seed is the first round of the game.

Randomness

First, hash the combination of the current round seed and the participated transaction ID in the previous round to create a random number.

Random number = hash (current round’s seed + previous round’s TxID)

Game Result

Random number for the round result is derived from a hash of the current round’s seed + the participated transaction ID in the previous round. Then the random number is divided by 10,000, which results in 10,000 different game scenarios.

Round result = Random number mod 10,000 = 0 ~ 9999
